/* ShadowConverge frontend stylesheet (Week 13.3 Step 3 visual redesign).

   Dark-only committed identity -- there is intentionally no light theme
   and no OS-preference color switching. The design principle is "color is
   signal, not decoration": the chrome is monochrome charcoal; saturated
   color appears ONLY to communicate verdict state (approve/reject/
   inconclusive/quarantined) and argument stance (for/against/neutral).

   Mobile-first; one breakpoint at 640px. Form controls stay at 16px to
   avoid iOS focus-zoom; interactive targets stay >=44px. Fonts are
   self-hosted Latin-subset woff2 (no external CDN -- privacy + the
   closed-source posture). ASCII-only. */
